Thanks, I was really happy with it and surprised how symmetrical it was.

 

I wasn't really going for a tail, the opposite in fact, I find them distracting. There was no coarse charcoal in the RP, I only used willow air float, it was also ball milled for 30 mins.

what I use to do is use a charcoal comp  for delay so after the tail burned as in the motor then it went dark for a second or two so it wouldnt take away from the shell.Extra work but as you go on youll find youll do all kinds of things to try

Thanks! But I was a bit disappointed with them, the breaks weren't that great and a lot of stars were blind. Hardly any of the Bleser blonde streamer to green lit at all which was surprising, lots of dark patches in the red/green peony, possibly because of the 10x10mm cylindrical stars I placed in amongst the burst charge.

This was my attempt at a smiley face pattern shell.
 

 

The 7mm stars were hot glued on to the 1mm thick cardboard template. 

 

 

Both hemis were filled with MCRH with no additional booster, then wrapped with 8 layers of gummed tape.

 

 

I'm not sure why there was so much delay, I've used the same passfire technique dozens of times without any problems... I think the rocket was on it's way down which is why it was upside down. The break was poor, more layers or booster needed.

Nice, it still worked. I never tried shapes before, just rings. I'd call that a success.
